Back Covers - TS2068 & QL Issue Disks 



OCTOBER EDITORIAL by Frank Davis 

Welcome to the beginning of another smashing year of QL, TS2068, Z88, and a dash of 
TSIOOO computing. I hope for this to be our best year vet A few o f you may not have realized it, 
but in the area of 5ie QL and the Z88, the maturity of Ae machines is beginning to pay off very well. 
In this issue and the next few I hope to show you just what I mean. I willnot be leaviM out the users 
of the TSIOOO and the TS2068 We will explore some of the options open to you and the future of 
these great little machines They can have a future, if you are willing to make it so. Many things are 
happemng to these compute.rs tliat those who have not patched into xht network of Sine lair users 
just do not know about. One way to stay atop all this is through magazines, such as Z88 EPROM, 
IQLR QUANTA, T/SNUG newsletter, user group newsletters, and most dear to my heart, UPDATE 
MAGAZINE! I honestly believe that UPDATE gives the most balanced, up to date view on Sinclair 
c omputers m the world. We are the only one I too w that now c overs them all - from the Z88, 
Spectrum, QL, QXL, TSIOOO, ZX81, TS2068, and one of our main areas is the disk systems 
available for these machines. We try to present user- genemted software that you can use, and have 
a place we can all come together to express ways of making these machines continue to be active 
and useful m our lives. They are not the latest whiz bar^ off the production line, this is true. But 
ecologically speaking they work and they can be upgraded in major ways, as opposed to thrown 
away! Most of the time another user or company can show you what to do. 

For now, I once again step down off my soap box to say hello to all of you. Carol and I 
have entered into our M year of editing and producing UPDATE. It seems to have changed in many 
ways from when Bill Jones first brought this magazine to life 7 years ago. In many ways it has 
remained the same, as a voice for Sinclair users. We try not to favor any certain machine or disk 
operating system, but rather to present all we receive that is fit and ready to print. In this way we 
give vent to all of the machines and try to balance the content. I even try to limit the editorials 
from rambling for to o many pages The editorial is meant to be the editors view on things and is the 
only chance I try to give myself. The rest of the magazine tries to be fair and objective on programs 
and hadware. If you do not see your particular DOS or drive system being actively supported in 
UPDATE, it IS because no one has submitted anything, not because I do not like it. Unlike some 
clubs or user groups where some folks try to be snobbish over which machine they think is best or 
should be the only one, we give credence to all of Sir Olives orphan children. 

Those of you who have closely read the pages of UPDATE and IQLR have noticed that the 
QL does not have quite as many programmers, hardware hackers and dealers as were here 7 or 8 
years ago . That is true. What we do nave now are much more sophisticated and useable hardware 
and software. Those who have used PERFECTION and TEXT8/ as word processors know that they 
are far bey o nd what we were 1 o o kin? at in 1 984-5 . Quill is still a g o o d pro gram, and no w even m o re 
readily available as EXCHANGE (the latest and fastest version of all four PSION pro erams all 
combined to work together) has been released to the Public Domain. It is notmy word processor of 
choice, as I like to use more fonts and sizes of type than it has available. Another example of 
program maturity is the case of LINEDESIGN and QDESIGN2, versus some of the early art and 
text programs for the QL. Both use vector fonts, which means that when enlarged, no clarity is 
lost. In earlier programs, they appeared choupy and grainy when enlarged, and smudged and hard to 
read when made smaller. Widi LlNEDESIGNyou can even import fonts meant for other machines. 
WithQdesign, you can purchase a Ve c to ]£dit program to create more vector fonts. Both allow the 
easy import of graphics and clipart. Publishers Pack from Text87 is another such wonder . 

Those who have a TS2068 will remember the early days of MSCRIPT and TASWORD, 
They seemed great at first, but soon were seen as hani to use and lacking in features as most of us 
migrated to disk based sytems Well, as you should all know. Jack Dohany has done wonders for 
h^CRIPT as a word processor, and it is now hard to compare it to the original. Larry Crawford, as 
well as a few others have done the same for TASWORD 2 for the Oliger and Larken. See his address 
elsewhere in this issue to contact him. Do please pay attention to the fact that neither one of these 
programs is in the public domain. To getanupgraae from either nerson should only be done by 
tho se who legally 0 wn the pro grams . At least buy a used copyofMSC RIPT o r TASWORD . B ye . 



REPORT ON THE DAYTON COMPUTERFEST 



BY FRANK W. DAVIS 

The last weekend of August found Carol and I on our way to the Dayton, Ohio 
Computerfest for 3 days of visiting, selling and motel living. This was the third year that 
UPDATE Magazine has attended this show and the fifth year that I have personally 
attended. We found this year, as in all previous years, the show was different. The 
number of people attending each year is sky rocketing. The first year I recall any figures 
was for 1 2,000, then 15,000, then 27,500 and around 40,000 this year. The show is for 
sure on a large increase in attendance. 

We got there Friday afternoon and hooked up with my partner in my other Sinclair 
enterprise, Mechanical Affinity.... none other than Paul Holmgren. He had beaten us to 
Dayton. He had already joined up with Hugh Howie from Canada, and Don Lambert 
from Auburn, Indiana, as well as Charles Reese from St Louis, to name just a few. 
We got settled into our motel room at Red Roof Inn, then contacted Tim Swenson, to get 
directions to his house. Jeff Moore, the last publisher of SyncWare News and Quantum 
Levels magazines, had left us plenty of boxes of TS1000, TS2068 and QL items, such 
as software, computers, and monitors, to sell for him. We got to Tims and picked the 
stuff up and then headed in a caravan following Paul to the Hara Arena, the showplace 
for the Computerfest. We arrived there and went through the usual hassle of trying to 
find your tables and unload your merchandise and get set up for the next day. They 
were a bit more unorganized at this point than in previous years. We got set up as much 
as was possible, and then headed back to the motel to get some rest before the show. 

Bright and early we got to the Hara Arena the next morning and proceeded to put 
prices on new items and uncover and set up what we had not done the night before. 
T/SNUG (represented by Don Lambert) was there sharing a booth with the Chicago 
Timex-Sinclair Users Group (represented mainly by Bob Swoger). Bill Heberlein and 
Neal Schultz of SMUG (from Wisconsin) had a couple of tables selling Sinclair, IBM and 
other related electronic and computer items. They have occupied the tables next to us 
for the last three years and are always welcome friends. The Dayton Sinclair SIG of 
DMA (Dayton Microcomputer Association) was mainly represented by Gary Ganger and 
Tim Swenson and had a table across and to the right of us. They have always had a 
computer museum, going from the early ZX80, ZX81 , TS1000, TS2068, TS1500, QL 
and all of the known clones except for a Thor and QXL. I want to thank this group for all 
the support they have done to give us Sinclair and Timex users a place to get together 
each year. THANKS. For the next two days we spent time selling hardware and 
software for Mechanical Affinity, and selling Subscriptions, QL and Z88 Source Books 
and back issues for UPDATE Magazine. I (Frank Davis) am also in the business of 
selling virus proof Shareware and Public Domain software for the Amiga line of 
computers. I had some of my more popular titles there with me. It did not seem to me 
that we had as much in the way of foot traffic at our booths as in past years, but those 
who came by definitely spent more money to upgrade than in past years. We sold a lot 
of Hermes, Minervas, Keyboard 90 Interfaces, lots of the latest software, and even some 
computers, ranging from at least one ZX80, three ZX81 s, two TS2068s and a three QLs. 
Sales of the Gold Card were still fairly strong, and we have also sold a few of the new 
QXL cards from Miracle that transform a lowly IBM into a speedy and large-memory QL. 
Part of this problem of lessened foot traffic could have been due to the fact that the DMA 
group had shifted around the floor space for some of the other booths, and added more 

space and then changed some of the Arena entry points. We were still in the exact 

same location as in past years. I hope it was some reason like that and not a sign of 
waning interest in TIMEX and SINCLAIR computers! Other changes of course dealt with 
the fact that too many of our users seem to more and more think that if an item or 
software is for an orphaned computer then the item should be for free, or dirt cheap. We 



3 



have to get out of that way of thinking and realize that a price should be fair, in order to 
keep programmers, hardware designers and dealers willing to put forth the effort for us 
that we need in order to expand and take advantage of future hardware and software 
developments. At the Computerfest, I saw this in relation to many computer systems 
other than our own. I saw IBM 286 computers systems with 20 or 40 meg harddrives, 
CGA monitors and 1-2 meg of RAM going (or attempting to go) for around $250, and 
Apple lis for under $100. Both were having a hard time getting buyers. They were easily 
worth that much and more, and would still have sold for more by mail order or in a store. 
However, at the show people thought these were too high of a price. With this type of 
attitude, it will be hard to get folks to develop new items for these machines. If you have 
not already done so, check out my editorial for this issue, for more thoughts on this 
subject. 

I find similar thoughts on occasion from some subscribers, such as one who wrote 
praising the content of UPDATE Magazine, yet telling me he thought it was priced too 
high. What he fails to realize, and may not even care about, is that magazines like 
COMPUTE, derive all of their income from ADVERTISING, not from the small rate they 
charge for a subscription. We do not have that many paid advertisers, and therefore we 
charge what it costs to produce the magazine and mail it to you. That is why we offer 
back issues at shows such as the Dayton Computerfest cheaper; we have no mailing 
costs at the show. I do welcome polite comments on this subject. Better yet get a friend 
a subscription to UPDATE as a gift this year (Christmas, birthday, maybe even as an 
extra anniversary present). That is the end of serious discussion, now back to coverage 
of the show. 

On Saturday night a goodly number of us gathered at Tim Swensons home for a 
cookout in his back yard. My thanks to Tim and his wife for their hospitality. It was a 
great time for eating and visiting. Who was there? I will try, but can not say for sure if I 
am leaving anyone out (if so then please forgive the oversight). Don Lambert from 
Indiana, as well as Carol and Frank Davis and Paul Homgren, also from Indiana; Bob 
Swoger from the Chicago area; John Impellizzeri and Don Walterman from Michigan; 
Jon Kaczor and Doug Gillespie and two others whose names have slipped my mind 
from the Cleveland area; David Lassov from Arizona; Neal Shultz and Bill Heberlein 
from Wisconsin; Harry Spencer from Alabama; Mel LaVerne and his son from 
Tennessee; and Keith Watson. I feel that ! have forgotten a least two or three of those 
who attended, but did not mean to slight you, I have just never had a real good memory 
on names (ask my mother and she will tell you she remembers more of the people I 
went to high school with than I remember). The picnic was a delight and the food was 
plentiful. Everyone chipped in and brought stuff to serve, and no one that I knew of went 
away hungry. In previous years we had gone to a steak house near the motels to gather 
for Saturday evening, but being seated at 6 or 7 tables makes it harder to conduct 
conversations or move around as we did at the picnic. Gary Ganger also attended. 

If all goes well, we hope to be at the Dayton Computerfest again next year. Carol, 
Paul and I have always enjoyed getting out to these shows to meet our customers and 
readers. We are also users of Sinclair computers. We liked them so much we kind of 
refused to let them die in North and South America. We do appreciate your support. 
There is just one thing that may get in the way of our going to Dayton next year. At the 
end of the show many of the other dealers in the flea market area were telling us that 
next year DMA was considering putting the user groups and flea market out on the 
parking lot or in a tent. Should this happen, I will not bother to attend at all. The show 
can go in the direction that it gives too much to the professional booths such as IBM or 
Microsoft, and forgets its roots - as a show started for user groups and a great flea 
market. 

BY THE WAY, LAST ISSUE I ASKED YOU, THE READERS, IF ANY OF YOU 
WOULD BE INTERESTED IN ATTENDING A SHOW LIKE IN NEWPORT. ANYONE???

"An Electronic Spreadsheet: Function And Application" 



- An electronic spreadsheet is to

what a jet plane is to the covered 
wagon. Cover the continent in a 
few hours (without error) not a few 
years with a lot of backtracking - - 

Paul Shelley 
SPREADSHEETS PART II 
Vol. 2:11 
"T.S. User Newsletter 

PREFACE 

Some people may seem 
undismayed by the aforementioned 
statement, considering that they 
have prior knowledge of what is an 
"Electronic Spreadsheet Calculator" 
(ESC) and that they know how to 
use it. 

However, for the rest of the 
people who can't or don't yet 
appreciate the significant meaning 
conveyed by this colloquial 
expression, it is for them that this 
presentation is primarily intended. 

My purpose herein will be to 
demonstrate that for the 

Timex/Sinclair family of 
computers there are ESCs capable 
of doing the two main things that 
an ESC was developed to do: 1 .) to 
handle "what-if calculations 
electronically and 2.) to serve as a 



general framewori^ with which to 
build "models" for the purpose of 
continually summarising, reporting, 
and analyzing, in matrix form, any 
financial, accounting, 
mathematical, engineering, and 
scientific manipulation of 
numerical data. And that the ESCs 
available for the T/S can be 
acquired for a fraction of the cost 
(and still carry as much "punch") as 
do the more sophisticated ESC 
versions for the higher priced 
computers. 

I will use an ESC that is for 
sale by my own company to 
illustrate the preceding facts to 
the experienced as well as the 
inexperienced user in the audience. 
Literature about this ESC is readily 
available. Though, it is hoped that 
the distribution of such literature 
will only be deemed academic in 
semblance compared to the 
illustration of this ESC as our main 
example throughout this 
presentation. 

PARTI 

In our first step toward 
demystifying what is an ESC and 
what its applications are I would 
like to begin by showing you what 
my ESC looks like from the start 
(See Fig. 1)

ZX-CALC 




(fig.i) 



As you can see it is basically a 
grid composed of columns (A-0) and 
rows (1-30); where each 
intersection (column/row) meets it 
is a place for holding some sort of 
data (e.g., a label, value, or 
formula) and these data 
compartments are referred to as 
"cells". 

The concept of an ESC is fairly 
new. The first ESC was introduced 
in 1 978 by a student at The Harvard 
Business School by the name of Dan 
Bricklin. Mr. Bricklin's idea was 
that a spreadsheet provided a 
"better way to perform endless 
recalculations of balance sheets, 
income statements, and forecasts 
required wheriever a single 
assumption changed." Reportedly, 
he modeled his first microcomputer- 
based spreadsheet program to "an 
electronic black-board and 
electronic chalk." His original wori< 
had 5 columns and 20 rows. Later 
on Mr. Bricklin teamed up with 
Robert Frankston who enhanced 
this first ESC by increasing the 
number of cells and developed some 
"user-friendly" features and packed 



the results into a 20K program for 
the Apple microcomputer. To make 
a long story short, this original 
invention was later named 
VISICALC and it is no secret that 
this software package went to 
become one of the most successful 
selling programs in the years prior 
to another popular integrated 
software tool called Lotus 1 -2-3. 

My company's ESC for the T/S 
is called ZX-CALC(or T/S CALC 
2000 for the T/S 2068). It was 
primarily designed after the 
VISICALC program. Not exactly as 
VISICALC, but similar in function, 
it can handle just about any 
procedure than the higher priced 
version. 

My first task is to 
demonstrate how my program 
handles "what-if, contingency 
calculations like the higher priced 
ESCs do. It is primarily with "what- 
if calculations that a spreadsheet 
proves its most salient advantage 
and versatility versus the vertical- 
statically-fixed formatted 
programs which offer a limited 
method for storing, displaying and 
manipulating numerical data. Also 
ZX-CALC has the ability to use its 
resources for producing any number 
of various display "models" that the 
latter programs do not have. 

"What -if calculations can be 
understood to occur in two set of 



circumstances. First a cell may 
contain data in the form of a 
formula such as: A01+B01 assigned 
toC01. By this I mean that the cell 
C01 contains the formula A01 +801 
continually, until the formula is 
changed or deleted from the 
program and that when you use the 
automatic-calculate option of the 
ESC the result of said formula will 
always appear in cell C01 and that 
the result will only vary if the 
values in cells A01 and 801 should 
happen to change. Second, the 
program may assign the formula 
A01 +801 to cell C01 , but do so by 
entering this formula in the form of 
an equation each time the final 
result has to appear. That is, in the 
first case the formula is calculated 
but it is also hidden and saved for 
later use by the program; whereas, 
in the second case no formula is 
hidden and saved by the program but 
it is allowed to be used and reused 
by manually entering it everytime 
the result is to appear in the 
designated cell (which in this case 
is cell C01 ). What is important to 
note from either "what-if method 
of calculation is that the final 
result of a calculation can be 
changed by simply recalculating the 
result-cell with the program as the 
data varies within the given 
formula. This ability to handle 
recalculations is what makes ESCs 
so unique in handling and displaying 
numerical data. Without this 
capacity to do recalculations there 



would be no other method than 
"backtracking" and using an eraser 
to change the intermediate and 
final results and later run through 
the entire calculation mode that 
was originally used to arrive again 
at the new intermediate and final 
total results of a given matrix of 
numbers. 

With respect to ZX-CALC it is 
the second set of conditions that 
apply regarding how "what-if" 
recalculations are done by it. That 
is, this program does not hide and 
save formulas in cells; It requires 
that an equation be entered 
manually each time you wish to 
recalculate the data in the ESC. 
There are six reasons why ZX-CALC 
has this mode of "what-if" 
recalculation. First, it has to do 
with speed. It approximately takes 
33 minutes to automatically 
recalculate the entire ESC. This is 
alright if there are numerous 
formulas scattered throughout the 
entire ESC, but in the case of just a 
few calculations it is preferable to 
use an equation that can generate 
actual results (e.g., sub-totals, 
totals, etc.,) within a matter of a 
few minutes instead of waiting a 
half-hour each time the ESC is 
recalculated. Second, there is 
usually (as in the case of another 
ESC known as VUCALC) a limit as to 
the number of formulas that can be 
included in an ESC. With ZX-CALC 
there are no limits to the number of 



9 



formulas that may be entered into 
the spreadsheet, since an equation 
is used to reenter the formula into 
a given cell each time the 
spreadsheet is manually instead of 
automatically recalculated. Third, 
ZX-CALC is an applications program 
and how it is applied presents a 
more flexible and dynamic style 
than a program that requires that 
cell addresses be included within a 
given cell and hidden and saved 
within same for further 
recalculation. That is, you can use 
and enjoy using it more so than if 
the "shoe was on the other foot.*' 
Fourth, though the program code to 
allow my ESC to operate in the 
first "what-if mode of hiding and 
saving formulae was written it was 
a matter of priority in calculation 
features included within the 
program that determined its fate 
primarily as a manually 
recalculatable ESC. For example, ZX- 
CALC includes a SUM function that 
allows one or more columns/rows 
to be added together to obtain 
subtotals, cumulative totals and 
final totals. Also my ESC includes 
a "replication" feature that allows 
cell data to be loaded or calculated 
according to one or more entire 
column/row, simultaneously, 
depending up to what cell address 
is "absolutely" or "relatively" 
specified in a given equation to 
copy a given calculation or data. 
Both of these two features were 
esteemed to be more important to 



calculation and recalculation 
procedures than including the first 
"what-if mode within the program. 
So the fact that ZX-CALC doesn't 
reference, hide and save formulae 
within a cell was a matter of trade- 
off between what comes first: 
versatility and speed versus simple 
"good looks," Fifth, there just 
wasn't enough room in RAM to add 
the first type of "what-if" mode 
into the program. But in short it 
wasn't necessary and it would have 
created (as I have already proven) 
certain disadvantages if it had been 
included. Finally, even though you 
are required to recalculate 
manually the spreadsheet there are 
no serious defaults in doing so, 
since the program is the one still 
responsible for handling the actual 
operational and mechanical control 
of a given equation whenever you 
attempt to recalculate the data in 
the spreadsheet. Therefore, the 
computer (not you) is what 
determines the final outcome of 
calculations performed with my 
ESC on a manual basis. 

PART II 

In this section of the paper I 
would like to focus on the valuable 
aspect of an ESC as a "model" 
builder using worksheets and 
templates to define and create a 
wide variety of frameworks with 
which a user may rely on repeatedly 



1 0 



to record and report data on more 
than one occasion in the same 
identical manner. 

To help us understand exactly 
what a "model" is I have chosen a 
particular accounting model 
package (sold by my own company) 
that makes use of the entire ESC ZX- 
CALC. The model is actually a 
supplementary application of ZX- 
CALC that serves to constmct a 
financial picture of a relatively 
small enterprise (such as a sole 
proprietorship) for the purpose of 
analyzing or forecasting its 
financial performance. The name of 
this accounting model is called 
R.F.R.G. - which stands for Ready 
Financial Report Generator. 

This model allows the 
generation of 10 different financial- 
status reports about a company's 
past business history on a 6-1 2 
month basis. 

What the content of this text 
is concerned with is a layman's 
explanation of what the 
terminology of the model means and 
what the model does. This will 
ease the process of summarizing 
and recording the essential 
numerical values next to each 
subcategory of each of the ten 
categories comprising this 
accounting model package. In turn, 
you can use the program to perform 
your calculations in order to fill in 



the necessary blanks. 

After the model has been 
entered into RAM then you fill in 
the appropriate blanks next to each 
template (i.e., Setl , Page-1 ). Each 
subsequent worksheet is Page-2 of 
the current Set with the next 
worksheet being Page-1 of the next 
higher-numbered Set then Page-2 
of this Set. . ..and so on. 

Within worksheets 1 , 2, 3, and 
4 we have the total picture that 
would generate a complete "cash 
flow" statement. This statement 
essentially reports the amount of 
money available, invested, how it 
was invested, and how much of it is 
left either in your pockets or left 
in a bank account. In worksheet 1 
we have 2 subcategories under cash 
flow, which are "cash" and "cash 
receipts." Cash is the actual 
amount of capital you initially 
decided to invest in your business. 
Interest is the revenue earned on 
cash invested in some kind of 
demand deposit: checking, savings, 
and certificate-of-deposit 
accounts. "Cash Beginning" is the 
sum of both cash and interest. That 
is, it is the money used to njn a 
company's total operations. Cash 
receipts are monies loaned, owed to 
and paid into a company by 
creditors, clients, or stockholders 
of the company, respectively. Cash 
receipts are monies that when they 
are available to and are used by the 
company they normally are applied 



toward some purchase or 
amortization of some debt that the 
company incurred due to its regular 
operations. In worksheet 2 we list 
the "operating expenses" of a 
company. Here we list the overall 
administrative and selling 
expenditures of a company, 
including the interest service 
charge a company must pay if it 
borrowed money at a specified rate 
of interest. (Remember, during the 
preparation of your financial 
reports you must set a definite, 
limited period of time during which 
these figures are compiled and 
recorded, therein). In worksheet 3 
you report the depreciation of all 
fixed assets preferably using the 
straight-line method. With this 
method take the cost of a given 
product-good, subtract its residual 
value (e.g., about 35% of original 
cost) and devide by the number of 
life-years you believe the given 
product will last. In worksheet 4 
you report total capital 
appropriations in order to obtain 
the sum of a company's financial 
burden. You then subtract cash- 
beginning from total disbursements 
to obtain "cash ending," which is 
the money a company has on hand, 
usually in the bank or are funds 
that it must borrow to meet 
current expenses. 

In worksheet 5 we have two 
reports. One is an "income 
statement". This report lists total 



sales and cost-of-goods-sold and 
subtracts them both to obtain gross 
profit and then subtracts gross 
profit from operating expenses to 
obtain total net income for a 
specified period of time. Next is 
the most essential report of them 
all which is a "balance statement" 
that reports a company's total 
assets compared to its total 
liabilities and stockholder's equity. 
By following each individual sub- 
category listed therein and 
referring to each preceding 
worksheet you will be able to 
record the proper figures needed to 
obtain a balance of assets-to- 
liabilities/equity. Worksheet 6 is 
simply the continuation and final 
segment of the "balance statement" 
report. 

Worksheet 7 is a display of 
various important financial ratios 
that serve as a quick guide to 
making current decisions and 
investment forecasts about a 
company's operations. In case you 
are unfamiliar with some of the 
terms used in this worksheet this 
is what they mean: (a full 
explanation of all labels used 
within the accounting model are in 
an Appendix enclosed with the 
package), Crt Rto, = current ratio; 
it is obtained by dividing current 
assets/current liabilities, Quk Rto. 
= quick ratio; it is obtained by 
dividing current equity /current 
liabilities. However, both ratios 



1 2 



must be stated in relation to the 
number 1 (i.e. if current assets are 
$90,000.00 and cun-ent liabilities 
are $35,000.00 then the cun'ent 
ratio should be displayed as 2.57:1 ). 
Equity is defined to mean the total 
capital stock plus the retained 
earnings of a company within a 
specified period of time. 

Worksheet 8 displays a 
"capital statement" which is the 
total capital assets of a firm less 
any cash withdrawals that may 
occur within a specific time period 
during which the balance statement 
was prepared. 



subcategories within this final 
statement. If necessary, however, 
any user may expand wori<sheets 9 
and 1 0 to include these other 4 sub- 
categories if they indeed do apply.

Both wori<sheet 9 and 1 0 
comprise a "woridng capital 
statement". This report serves to 
demonstrate whether or not 
administrative expenses are 
covered by the monies obtained 
through the sole income earnings of 
the company without relying on its 
net equity. In this statement, 
though it does not appear therein 
you may also report (under "woridng 
capital provided") the monies 
obtained through the sale of a 
company's fixed assets as well as 
any deferred income tax taxes and 
withholdings of employee's salaries 
and wages and the sale of capital 
stock in the company. Since this 
accounting model is designed 
mainly for a sole proprietorship 
like my company is, I felt that it 
was not necessary to include these

Whfle there are a few "Data Base" 
software for the 2068 such as PROFILE, I 
opted to roll my own simple program. This 
program can be used for any record keeping 
or filing such as video cassette Ubraiy, 
telephone directoiy, floppies, CDs, 
addresses, membership list etc. As written, 
the program will keep 1000 records 32 
characters each with 3K of memory left over.

© Start a NEW records file. 

© Add or UPDATE a record. 

LIST the records to the screen starting 
anywhere in the file. 

O FIND a record or title by ENTERing 
the first 3 characters or digits. (It is fast!) 
© SEARCH (wild-card) by ENTERing let- 
ter(s), number(s), or a combination thereof, 
especially if the spelUng is unknown, the

the end of the file. 

H Lines 720 to 780 search for a match at 
the beginning of each record of the three 
characters INPUTed and lists them to the 

screen. 

Lines 890 to 970 search for a match in 
every record of the character(s) INPUTed 
and lists them to the screen. 



H Lines 1000 to 1025 delete any empty 
record cell that becomes record #1 after the 
SORT routine is completed. 

H Lines 3000 to 3040 prints to the screen 
the record to be corrected and provides 
INPUT for the correct record. 

H Lines 4000 to 4050 are for printing to a 

large printer using the LarKen disk inter- 
face to set the margin and 132 columns, 
also sets a Tandy DM? 105 printer to print 
in condensed font. For a 2040 printer 
DELETE 4000,4035. Change line 4050 to 
4050 RETURN. 

H Lines 8000 to 8160 sort routine by the 
first character of every record in this or- 
der:- Blanks/spaces, Numbers then Al- 
phabets. When the sort is completed all 
blank records will be at the beginning of 
the list To remove the blank records, use 
GO TO 1000. 

H For other than LarKen users, lines 180, 
4000-4050, 9000, and 9010 will have to 
be rewritten accordingly. 




DISI>LAY BLOCK!— MO V3ES

In the Z80 microprocessor used in the 
2068 is a command called LDIR that may be 
used to quickly move defined blocks of data 
from one RAM location to another. The rou- 
tine listed below moves all or portions of 
the screen display (DFILE1) to RAM address 
30000 from which it may then be moved back 
to the display file. 

Because of the manner in which pixels 
and attributes are addressed in DFILE1 , the 
simplest way to define a block to be moved 
is either the whole DF1LE1 file, or the 
top, middle, or bottom third of the file. A 
pixel-by-pixel or line-by-line block-move 
requires much more complex definitions. 

Some uses for this technique might be to 
insert text or graphics into a menu or to 
do animated displays. While the number of 
such displays stored in RAM is limited, 
many more may be saved to disk. This is a 
revision of an original article I wrote for 
the May-June 1985 SyncWare News.

PRO/FILE - ON THE QL 



by Kzjtton Gcuulq^ 



Database Pro/File does not need any introduction to the Sinclair 
enthusiasts here in the USA. It was the most popular program of 
our Timex/Sinclair 1000 (ZX-81) and T/S 2068 (Spectrum) computer 
youth. 

Unfortunately Pro/File was never converted to QL use; but it has 
been Upgraded, Renamed And Rewritten In MSDos & Atari. 

PC~FINDEX 5.0 is the latest upgrade Dos version; and yes, thanks 
to the Gold Card & PC Conqueror - It Does Effectively Emulate On 
The QL! Best of all Findex is still the same Average User Data- 
base Concept that was the hallmark of Pro/File's success. 

Findex is unique in that it is completely unfettered - no fields 
sub-fields or restrictive pre-design requirements; and yet it is 
a powerful program, designed to permit the inexperienced user to 
easily and effectively create any type of database desired. 

When using Conqueror with DRDOS it is necessary to add, "Command 
Com", to Findex. Easiest way, is to add the "/S" Switch to your 
normal Format Command - when Formating a blank disk, to make the 
back up (working) copy of Findex. The "/S" Switch instructs the 
QL to Automatically Add "Command Com" during the formating proc- 
ess. (Reference Pages 240-244 DRDOS 6.0 User Guide) 

Eg: With ED Drives And A 3 1/2" Double Sided/Double Density Disk 
The Format Command Would Be Format B:/F:720/S . The Step By Step 
Procedure Is: 

1. Load PC-Conqueror From Drive "A". 

2. Load Your DRDOS Operating System Disk From Drive "A" 

3. Leave The DRDOS Disk In Drive "A" And Put An Unformatted Disk 
In Drive "B." Type Your Normal "B" Drive Format Command WITH 
ADDITION OF THE "/S" SWITCH.

first of April, please do not dispair, we will get to it soon! 

Some of you ssay have noticed by now, this little newsletter is now 
going to be carried as a regular feature in THE PLOTTER to replace 
the long-running BITS & BYTES column that I have been writing for 
many years. It makes more sense, as I was writing this news page 
and then virtually retyping it into the BITS & BYTES format 
anyway. Let us know what you think. He are not after free

ARCHIVE SERIES 
PART 14 : ENTERING PROCEDURES USING THE 
ARCHIVE PROGRAM EDITOR - THIRD GROUP 

We are starting to build a large program now. This time I 
am introducing several new procedures to our basic user 
interface procedures now saved as group2_prg. We will 
call this new set which includes all of our group2 plus the 
new procedures - groupS I am not being specific about 
what kind of program we are ultimately making because I 
haven't made up my mind yet. The procedures we are 
adding this time are still of a general nature and will be 
useful in many situations. Feel free to contact me if you 
have a request for a particular kind of ARCHIVE program 
to be developed in this column. 

PREPARATION 

Start ARCHIVE in your customary way so you see the 
ARCHIVE command prompt (>). You will load the group of 
procedures entered last time and saved in a file called 
"group2". Then we will start the editor and begin entering 
the first new procedure called "close_aH". You will 
continue entering the rest of the procedures plus 2 testing 
procedures called "test2" and "test3" to illustrate how the 
new procedures can be used.

If you make a mistake while entering the listing below the 
editor may not accept the line and you will have to spot 
the mistake and correct it (like unmatched quotes). Also 
the indention's should match the listing if there are no 
mistakes. Type in as much as you wish at one time and 
exit the editor and save the file with the name group3 and 
save a second copy somewhere else Remember to load 
group3 when you are ready to continue your work. Test2 
illustrates the directory related procedures and test3 
illustrates the field_display procedure used with the 
by_arrow procedure entered last time. This allows us to 
access a particular field of a database using the arrow 
keys or the first letter of the field name. Most likely you will 
have mistakes to find (debug). The basic steps are : 

load "{}gmup2"<ENTER> Load previous work {}=device

QLCORie 



This summer I spent much of my time learning to use the many new 
features of XCHANGE and XCHANGE Quill. Some of us had expected an 
XCHAN6E manual to surface somewhere so that we could use XCHANGE more 
efficiently. This never happened. 

I decided to look closely at the five HELP files (those ending with 
an _hob extension) and decided to re-format them, select those files 
pertaining to the new commands and printing them out. After working 
with XCHANGE for several weeks, I added some text to the file I call 
XCHNOTES. XCHNOTES_doc file is approximately seven (7) pages long and 
will do for now as a user's manual. 

XCHANGE Quill, Archive, Easel and Abacus are updated versions and 
seem to operate faster than the latest versions of the same named 
files. When in XCHANGE itself, multi-tasking with additional software 
isn't a problem. I now use XCHANGE instead of Taskmaster and 
multi-task The Editor S. E. without any problem. 

The mail merge facility in XCHANGE Quill will allow the use of a 
Name and Address file from either Archive or Quill. So those of you 
out there who do not use Archive will find a simple _doc file 
adequate for use as a database. Incidentally, using this mail merge 
is a lot easier than using a mail merge from a separate Mail Merge 
program . 

I. can supply any reader of LIST with a copy of XCHNOTES_doc or 
XCHNOTES_txt and all five HELP files formatted as _txt and _doc files 
6n disk provided you send me a formatted, 720K disk (either 5 1/4 or 
3 1/2") in a suitable envelope so that it can be used for return to 
you and return postage which is usually 75 cents in stamps. If you 
need the XCHANGE program, send an additional formatted disk with 
enough return postage. I will send out the software the next day 
after receipt of your request. 

If any QL user is still suffering from a QL overheating problem, I 
have on hand a small supply of the 2 Amp version of the ^ 78C05 
voltage regulator. (Original version is 1 AMP). The European s have 
used this fix for quite some time with good results. Here in the 
'States' they were not available. If any one needs one, send me $3.00 
and I will send you one, post paid. 

Digital Precision has sent me the latest version of The Editor S. E. 
to review for IQLR . I've been using The Editor since 1987 and 
upgraded to the Special Edition in 1988. This is the only 'word 
processing' software that I need. At times I prepare manuals ranging 
from 20 pages to approximately 200 pages for some friends in the 
air lie entertainment industry. All pages are printed out 
back-to-back. The Editor. SE handles this very well. Any control codes 
required (bold, double height-width, italics, letter quality, and so 
on) I embed directly into the text while proof reading. This can be 
done quite easily since The Editor has a special character set which, 
when used for control coding, the printer understands and follows 
through by printing out these commands correctly. 

Those of you who use The Editor SE , and don't know whether you have 
the latest version or not (all SE versions are 2.05 regardless of the 
upgrade), look at the byte count for the XTRAS file. My original SE 
version of the XTRAS file indicates SK 598 bytes; the newest ^©^-sion 
indicates 7K 268 bytes. There really aren't any new commands J^^ded, 
however many of the commands have been 'tweeked' or improved. The 
boot file now activates several Lightning files which are included on 

27 



the disk, for faster operation of the software. Digital Precision 
will upgrade The Editor SE for you for a slight fee. 

Digital Precision has also upgraded PC CONQUEROR (PC ^^^l^l^l^ 
operate with more memory when using a Gold Card. This program is 
called PC conqueror Gold Special Edition which allows the user with a 
Gold card and ED disk drives (3.2 Meg) to get the most out J-^^^ PC 
emulator. I understand that this edition will also support hard 
drives. 

Most of the new software being developed recently operates with Tony

QLUSTer 5.105 
by Al Feng 

QLUSTer has recently undergone a long awaited upgrade which had 
been partially delayed by a year of voluntary service (servitude?) 
on the Eastern Navajo Reservation. As the version number would 
suggest, QLUSTer has undergone a significant change, the most 
important of which is easy access to already "made" sub-DIRectories 
structures . 

QLUSTer requires that your QL have access to five SuperT00LKIT2 
keywords: WCOPY, WDELete, SPooL, RENAME, WSTATus. 



Sub-DIRectories [ ... -> ] 

Access to the sub-DIRectories is performed by simply pressing the 
appropriate key designate as you might for an individual file. 
QLUSTer will determine that it is NOT a file, and go about the task 
of retrieving and displaying the sub-DIRectory . 

The sub-DIRectory will be "in play" even if you change the device 
to a floppy which does not have a sub-DIRectory structure. The net 
result may be an empty page if no files exist with the appropriate 
DIRectory prefix. 

Return to the main DIRectory via a SELECT_DEVICE option (press '0' 

to access ) . 

If the disk you are using has sub-DIRectories, but your QL does not 
have not have a sub-DIRectory structure [i.e., " ->"], then QLUSTer 
will (at last attempt) simply access the first file in that 
sub-DIRectory. The subsequent files will not be accessible other 
than via WCOPY or WDELete. 



Greater "crash" protection 

Time away from Qomputing has helped me resolve the problem of my 
version of TURBO (2.00) implementing file type recognition. It is 
believed that the only reason QLUSTer will hang-up/crash now is if 
the EXECutable file is corrupt and does not load properly. 

QLUSTer will also "ask" whether or not your printer is READY before 
it will attempt to send a file down the line.

QLuMSi DOS v4.20 
by Al Feng 

QLuMSi DOS (QL . using . M' cr~S~ft . inter face Disk Operating Simulation) 
has, as the version number might suggest, recently undergone a long 
awaited upgrade which had been partially delayed by my year of 
voluntary service (servitude?) on the Eastern Navajo Reservation. 

Version 4 of the QLuMSi program has added the following commands: 

CD \ 

CD \lsub-DIRectory_pre£ixl 
MD \|»ob-DIRectory_pre£ixl 
RD \lsub-DIRectory_prefix] 

Most people with a QXL, GOLD CARD and FLP/RAM chip should welcome 
the ability to access sub-DIRector ies . 

The 'MD \* command (with a "sub-DIRectory^name" ) will initiate the 
MAKE_DIR commmand and MAKE a sub-DIRectory on the medium. For 
example (you may want to try this on a dupe of your master disk), 
at the prompt, input the following: 

MD \FAST 

When you input *DIR' (presuming you have appropriate TK2_code) you 
should see: 

FAST -> 

in place of FAST_Disk and FAST_doc. 

The 'CD \* command with a sub-DIRectory_jpref ix will access: 

a) the sub-DIRectory on the medium; or, 

b) any other valid prefix. 

Thus, if you were now to Input **CD XFAST** (after performing the 
above example), you would see: 

A:\FAST\> 

Now, inputting "DIR" will show you the two files along with a 
data-file, e.g.: 

FAST_Dlsk 

2758 1993 Sep 19 17:00:00 
FAST_doc 

4096 1993 Sep 19 17:00:00 

FAST_ 

64 1993 Sep 19 17:00:00 

The 'CD \' command (without a sub-DIRectory_pref ix ) is used to 
return to the main DIRectory. 



50 



The 'RD \' command (with a "sub-DIRectory_name" ) is used to REMOVE 
a sub-DIRectory from a medium. 

NOTE: If you have several sub-DIRector ies with similar "names" 
then you may be asked whether or not you wish to REMOVE 
them also^ e.g. : 

RD \ LETTER 

will prompt you if you wish to REMOVE the sub-DIRectory 
name LETTER as well as LETTERS (for example). 

NOTE: If there are files in the sub-DIRectory^ the sub-DIRectory 
will not be REMOVEd. 

As before, those more familiar with the standard DOS commands may 
opt to utilize the smaller COMMAND_COM version of the program. 

Both the **full" version of the QLiiMSi program as well as version 4 
of the COMMAHDjCOM program require that your QL has the MAKE_DIR 
command available to it in addition to the traditional TK2_EXT 
code . 

To accomodate those who either do not have a QXL, GOLD CARD, or 
PLP/RAM chip, a version of the new QLuMSi program has been included 
which does NOT require MAKE_DIR (hence, will not allow you to "MAKE 
(a sub- )DIRectory" on a medium. This is the QLuMSijCOMn program 
you will find on your master disk (use BOOT_ALT) . 



QLiiHSi printing 

In the current version, indicating the device as either COM or LPT 
still presumes SER. This may-or-may-not be an inconvenience for 
QXL users as my understanding is that some of the i/o drivers have 
not been written yet. 

I will make necessary changes in the future as information becomes 
available. to me.

QXL CARD for the IBM - This card has a 32 bit 68EC040 processor running 
at 20 MHz and we are offering them in 2 meg, 5 meg and 8 meg RAM sizes. 
The processor has access to its own RAM so performance is virtually 
independent of the host PC (so it could be an 8088 or 486, etc). Under the 
QXL your PC becomes purely an I/O system giving QL programs access to the 
PCs floppy disk, hard disk, keyboard, display, serial and parallel ports. The 
QXL has 2 QL style network ports to allow connection to a QL network. We 
offer these cards with a two year warranty, and will automatically send you 
free of charge software upgrades for the system. The operation is easy; install 
the card, insert the disk, and type "QXL" and your PC will appear to be a 
QL...a real upgrade. The price for the 2 meg is now $460; the 5 meg is $540; 
the 8 meg is $650. The lower meg ones can be easily upgraded by changing 
memory chips. 

TEXT87PLUS4 Version 4 - This is the very latest version of this popular word 
processor for the QL. It now checks to see if you want to use the standard 
dictionary or add your own word list; the initial menu now includes the ability 
to IMPORT as an option; now before a file is saved all residues of aborted 
Typefaces are removed; dimensions and co-ordinates are now rounded off in 
Layouts (rounding off also takes place when you change the length unit; and 
now when you zap a document the text sections are retained, together with the 
rulers and layouts, thus giving you a complete skeleton document for adding 
text. These are only some of the enhancements in this new version. We are 
offering all of this for only $119. We also have 2488, the printer driver for 24 
pin printers and bubblejets for only $29; the Typeset90 - deskjet driver for HP 
deskjet printers for $29; and Typeset90 - Epson Laser drivers for $59. 

LINEDESIGN from PROGS - this is a vector drawing program which uses 
outline fonts and clipart , and allows you to move or resize text or art without 
losing any print quality. It comes on a ten disk set of the main program, plus 
many fonts and clipart. It can be mouse controlled and gets even better the 
more memory you have. The price is $149. 

PROGRAM TAPE SPECIAL FOR THE TS2068 AND TS 1000 - 4 program 
tapes, our choice and all different, for $3 and this includes postage. Get 6 tapes 
for only $4. These are all commercial programs and only 300 available. 

128K RAM CARTRIDGE FOR THE Z88 for only $40.

QL TIDBITS AND TIPS SINCE 
THE LAST ISSUE by e. ^, 

There comes a tiae when im^ people (not jut ay 
couseli&i clie&ts) \m asked e&oii|li questions about SLs 
and related items that I ieel I need to share what I ha7e 
found out with the rest oi ;oq. I have not been able to get 
^od answers to all of the (usiions asked, but I will relay 
those 1 can answer or |et answers from Frank or Paul on. 1 
shonld at this point mention to all of our readers, that I 
will offer help when and where I can, if it does not take a 
large amonnt of time. I know that the best place to |et 
answers is often the dealers, bnt always remember this one 
point:: IS IT FAIR TO ASE A DEALER YOU BATE NOT 
DONE BUSINESS f ITB TO ANSWER BDESTIONS 
ABOOT BOr TO SET UP OR USE TEE SOFTWARE 
TEAT YOU PURCEASED ELSETEERE? YOD ARE 
ASEIN6 TEIS DEALER TO SPEND BIS TIME TO 
ANSWER QUESTIONS FOR SOMEONE f BO DOES NOT 
EVEN DOTBER TO BUY FROM BIM. I hafe talked to 
three dealers recently who have reported this as a growin| 
problem, being inundated by people who have pnrchased 
products from ontside of North America, and then expect the 
North American dealer to take his time to show them how to 
get it to work. Most reason that it is cheaper to call or 
write here than omseas. 

I at one time did most of my purchases from overseas, 
and sent repairs to be done over there. The service was 
good, bnt I decided that this sort of thing wonld kill off the 
few dealers and repair facilities we had here, so I changed 
my ways. In North America we have A.F.R. Software still 
herej RME Enterprises, Dan Elliott's excellent repair 
facility, Mechanical Affinity, food and find Compntlng to 
name the ones that first come to mind. Give them the 
business if yon want snpport from them, and they will all 
try to do right by yon. It might even help the balance of 
trade for ns by keeping the mailing costs and small bit of 
profit here in our hemisphere, rather than elsewhere. As 
many of yon have realized by now, Canada and the USA 
have definite ideas about how to play fair in business, but 



some countries seem to scoff at such old fashioned ideas as a 
level playing field. This has hurt the economy of North 
America. I do my bit by buying here when I can, and 
avoiding those who are the worst offenders, such as Korea, 
Japan, China, and France. Most of what we get for our BLs 
and ZSBs has to come from England, Belgium, Denmark and 
Germany, who are fortunately plaj^ng a bit more fair than 
the other mentioned countries. 

I do not believe I have made such a strong 
economical-political statement since my bys as a college 
student. I will only say it this one time. End of subject. 

Now for the technical end of things. Frank got a 
letter from a user recently wanting to know about usii^ the 
serial printer with the Miracle BiL card. You need to use 
COMS I to be able to use the serial printer on mine. This 
may already have been updated and made easier by the time 
you read this, as Miracle has been working very hard to 
finish all the drivers, etc. for the BZL cari 

Another BZL question that has come up is how to 
chauge the 2 meg version of the card to a 5meg or 8 meg 
version. It can be easily done by those with some electronic 
hobby experience, or lacking that take the purchased chips 
and card to your nearest electronics repair shop, along with 
this article. To go from 3 meg to 5 meg: Swap 8 of the 
DRAMS, by swapping every other one with the new ones 
starting with the one nearest the bracket. To |o from 2 meg 
to 8 meg you need to replace all of the chips. They are 
ZIPPS and should be 80 nanoseconds or better. I replaced 
the ones in mine with ones that were 60 nanoseconds and it 
works great. Some software has already been updated to 
take advantage of this large amount of RAM, and the 
facilities for QL users who want to put these cards on an 
IBM compatible, and I am looking forward to more such 
improvements. 

Al Feng wrote to Frank that the Keyboard 90 
Interface he got from Mechanical Affinity to use with a 
ZEOS RS keyboard and his BL, had some keys not properly 
working. Be had lost some functions, such as the lack-slash 
and the vertical line and finding the tilde and the pound 
stsrl'ajdjn being the resulting output. The answer should 
be the following: a) shift nrticiirutt eguJs kd-slisi t) 



34 



ab87e TAB, next to the 1 key is where yov shouli find the 
back-slash key. This does not seeo to be ROM dependent, 
jnst the wirini setnp for the Keyboard 90 Interface. It is a 
m setnp once yon ^t nsed to a few small quirks like this. 

Anyone ont there who has tried or wanted to p\ the 
new proiram LINEDESIGN, bnt were pnt off becanse yon 
were nsin| a Canon BJl OE and thon|ht it would not work 
with that, let either PROGS or MECHANICAL AFFINITY 
know and they will get yon a driver that will work with it. 
This is a program that appears to have great potential, and 
I expect to see some newer versions come ont over the next 
year or so, to which the upgrades will probably be free or 
lowcost (this may not be the case in a major upgrade 
version, it may cost a small amonnt at least). As the 
program is right now it is the best in its category. Some of 
the fonts on a 9 pin printer are not qnite as good as some in 
Text87Flns4, bnt with a Bnbblejet or Oeskjet or even a 
Laser printer they are magnificent. The way FROGS has 
done upgrades in the past it would be best to get one of the 
versions, and upgrade later. Then a major change comes 
out, it may cost more than the combined original program 
and upgrade cost. The fact that you can import Adobe 
Illustrator files to the program is quite a plus. Some folks 
have already had remarkable success adding new fonts to 
the program. That else can you say about a BL program 
that comes with manual and 1 0 disks. 

To answer my own question an issue or two ago about 
using my Canon BJl OE with Text87Plus4, the new version 
with Software 87's new program Publishers Pack comes 
with two new extra items. One is an upgrade on 
Text87Plus4 (the program only costs $59 and is worth 
it)which contains many new enhancements to the program. 
The other new item is Fountext93, a new high resolution 
upgrade to Fountext88 which prints at 1 80 Z 1 80 dots per 
inch on 24-pin and bnbblejet printers. It also comes with 
ready-made-page-layout objects such as shadowed 
boxes that you can start preparing professional looking 
publications. Publishers Pack combined with LINEOESIGN 
combines the text editing and printing capabilities of 
Text87 with the graphics and font handling ability and 
power of Linedesign. The North American distributor for 
these is Mechanical Affinity. This can all be purchased 
together as Plus4 Publisher, and comprises the Plus4 



wordprocessor, LINEDESIGN, and Publishers Pack for the 
price of 1 99 pounds sterling or $295 DS$. 

By the way I got Software 87's program 2488 to 
work for me and my bnbblejet, it was a simple matter of 
having the correct setting on the little pins inside the 
printer. Experiment around with them and you will learn a 
bit about what pin settings on a printer can do. Make sure 
yon write down what your original settings were so that you 
can reset it if needed. I use my bnbblejet a lot when 
traveling, but at home and office I use my HP Deskjet Plus. 

A tip tor those using inkjet type printers that will 
improve your printouts, or originals used for photocopying. 
You will do best with inkjet paper. It is a special clay 
coated paper and helps keep the ink from smudging and 
appearing fuzzy. Tith this special paper you will get 
sharper printouts. /This also applies to the older Olivetti 
inkjet printers and color inkjets. If it is not available in 
your office supply store, ask them to order it for you. It 
costs more, but it is worth it for printing those things that 
you care about the appearance of. 

Those of you who purchased a copy of SER Mouse 
over 6 months ago, if you have not got it up and running, 
should check with Jochen Mertz or Mechanical Affinity and 
get the latest version, with new manual. It is best to send a 
few dollars or german marks to cover the cost along with 
proof of purchase. The newer version seems much improvei 
I am still hearing from people who think it should work 
with non-pointer environment programs....not with out some 
reworking of those programs. If a program does not support 
a mouse or pointer environment, do not expect the mouse to 
do all you think a mouse should do. Programs are becoming 
more and more pointer environment friendly, but not all are 
there yet Some of them may never be changed to that. 

I have heard that Parker Lewis has found the same 
bug (or at least nuisance in Text87 1 have found. Then 
used with a nine pin printer, my old Seikosha, it will not 
give me any fonts that are simply double height. I would 
like to be able to use such when I use my older printer to do 
labels with. 

Does anyone out there know how to do business cards 
with the Deskjet or Bnbblejet? I can get sheets of blank 
single sheet business cards, but am not sure of how to either 
format, or program to use. EFT

SUPERBASIC 
DATA TYPES 

Whenever we use variables in a 
SuperBasic progrann, we tell 
the SuperBasic interpreter what 
typeoi data it may hold in each 
variable, We don't necessarily 
do this deliberately as the 
system 'defaults' to a particular 
type But what is a type and 
how do we take advantage of 
them? 

It's all to do with data 
representation; it we're dealing 
with numbers in an accounting 
program, we're likely to want to 
use fairly large numbers which 
may optionally include a 
decimal point, If we were 
writing a program to look after 
the stock levels in our factory, 
we'd probably waht to use 
whole numbers, and if we're 
writing an address book 
program, we want to deal with 
strings of characters These are 
the three fundamental data 
types accepted and used by 
the SuperBasic interpreter. 

The first type, numbers which 
may include decimal points 
and can take on extremely 
large values, is known as 
floating point On the QL, 
floating point numbers have a 
range of in the region 1 0 to the 
power of ±61 5. 

The second data type, that 
comprising whole numbers, is 
known as the integer dala type. 
On the QL, integers can be any 
whole number between 
32768 and -32767 

The last type, comprising of 
strings of characters, is known 
as the string data type, and 
strings can be from zero 
characters long (known as the 
null string ie, "") up as far as 
32766 (NOT 32767!) 
characters long. 

The reason for the existence 
of the three types is that 
different applications demand 
different kinds of data, and 
having to hold all data as "one 
particular type would be very 
inefficient, QL SuperBasic 
variables are specified in terms 
of type by following the name of 
the variable with a special 
symbol If there is no symbol, 
as in 

variable 

then the data type is floating 



point As it is implied rather 
than specified, this is the type 
adopted by default 

Integer variables are 
introduced by following the 
name with a per cent sign, as 
in 

variabte% 

and string variables are 
created by terminating the 
name in a dollar sign: 
variables 
The SuperBasic interpreter 
exercises something known as 
type coercion, which means 
converting data from one type 
into another. For example, we 
may have a variable, v. which 
holds the number 23, As v^has 
no special symbol at the end, It 
Is a floating point variable. This 
means that Its value, 23, is held 
as a floating point number 
Inside the QL. Nevertheless, we 
can put the value Into an 
integer variable 

x%=v 

because the value of v(23) also 
happens to be a valid value for 
an integer. The SuperBasic 
interpreter coerces the floating 
point representation of 23 into 
its integer representation 
before the value is placed into 
x% This coercion is often very 
useful, as we don't need to 
check for operations such as 
the assignment above, and old 
BASIC functions such as STR$ 
and VAL are done away with. 
To see whether a coercion 
could be successful, we need 
only to consider the generality 
of each type. As a string 
variable can hold an arbitrary 
string of characters, and as all 
numbers may be written down 
as characters (and therefore 
stored as characters), it follows 
that a string variable can 
always be assigned a numeric 
value. The statement 

v$= 1234.56 
will put the seven characters 
"1", "2", "3". "4",",", "5" and "6" 
into the string variable v$ The 
value of 1234 56 (ie, the 
number 1234 56) will not be 
stored, simply its string 
representation The string data 
type is therefore more general 
than numeric types such as 
floating point and integers. 

Floating point is more 
general than integer, because 
every integer may also be 



represented as a floating point 
number This makes the integer 
data type the least general and 
string type the most general 
There is a further data type 
accepted by the SuperBasic 
interpreter, called the name 
data type. This is used for 
procedure, variable and 
function names, and for file and 
device names It is comprised 
of a string of characters, just 
like the string data type, but is 
slightly less general than string 
as not all strings are valid 
names It is used whenever you 
specify a filename, as In 

0PEN#3,mdv1-myflle 
As you can see, the only 
difference between it and a 
normal string is that it is not 
surrounded In quote marks. It is 
perfectly permissable to add 
the quote marks, and thus turn 
it into a string, but it Is generally 
less convenient to do so The 
name data type is a sub-branch 
or leaf of the string data type 

UN-TYPED DATA 

Occasionally you will come 
across instances of data which 
don't seem to have a type 
specified at all. Although you 
may think that this makes it _ 
default to the floating point 
type, this isn't quite true 
l^et's take a typical defined 
function: 

1000 DEFIne FuNction 
MYFUNC%(a,b) 
1010 LOCalc,d$ 
1020 c=alNSTRb 
1030 IFc=OTHENd$=" 
ELSE d$= 'OKAY' 
1040 RETurn LEN(d$) 
1050 END DEFIne 
If we make a list of all the 
identifiers (names) in this 
function, we see MYFUNCX, a. 
b, c, d$ The function itself, 
MYFUNC%. is terminated in a 
% sign, which indicates that the 
function is typed. It returns an 
integer result Likewise, the two 
local variables c and d$are 
typed; c is a floating point 
variable and d$ \s a string 
variable. What about the two 
formal parameters, a and b? No 
type is specified for them, yet 
they are used as string 
variables vyithin the function. 
This is another rule of the 
language followed by the 
SuperBasic interpreter: formal 



parameters to functions and 
procedures are un-typed, and 
the actual type is derived from 
the usage of the variables 
within the procedure or 
function. As we're using them 
as strings here, it doesn't 
matter what type the actual 
parameters are as string is the 
most general type. If we had 
used them as integers in the 
function, we'd get an 'Error in 
expression' error (or possibly 
'Overflow') if the actual values 
of 'a' and 'b' could not be 
coerced into integers. 

There is nothing to stop us 
specifying the types of the 
formal parameters within the 
function, as in 

1000 DEFIne FuNction 
MYFUNC%(a$,b$) 
but as the interpreter still 
follows its own rules, the type 
we specify will be over-ridden 
by the type dictated by the 
usage. 

The reason for having un- 
typed formal parameters is a 
little obscure, but as it makes 
little difference to the way we 
write programs it doesn't really 
matter Some of SuperBasic's 
rules for typing DO affect us, 
though, and if we don't know 
about them it is very easy to get 
confused The main point to 
watch is the 'flow of control' 
statements 

SELect 
REPeat 
FOR 

Each of these hias a 'control 
variable' (or, nrore accurately, a 
control identifier) which is 
specified in the construct: 
SELect ON var 
REPeat /OOP- r 
FORx=0TO10 
The important thing about these 
control variables is that in all 
three cases they f^UST be 
floating point variables We 
cannot have 

SELect on var% 
or 

REPeat loop$ 

The annoying thing is that if we 
enter such an error>eous line 
into a program, the SuperBasic 
interpreter won't complain. 
Things will go wrong as soon as 
we run it, though, and the 
particular error generated may 
be extremely obscure So 
watch out! 



QL com 



Great news for QL Users! Psion, UK has declared XCHANGE, a suite of 
four bundled programs, (Quill, Archive, Abacus and Easel) as public 
domain software. All QL and QDOS users can freely distribute copies 
among their groups for personal use. The version of XCHANGE being 
distributed is 3.90 which was rewritten and produced by Dansoft for 
the Thor computer (a QL in a PC case). 

My understanding is that each of the five programs (Xchange, Quill, 
Archive, Abacus and Easel) have the latest upgrade which include 
addi t i ona 1 c ommands . 

The Xchange file is approximately 183K, which will only operate with 
disk systems as the file is too long to be placed on a microdrive 

cartridge . 

Thanks to LIST member, Joe LaPuiizina for providing me with a copy of 
Xchange . 

The diskette has many files on it, which includes a disk editor, a 
file editor, a screen dump utility with many different printer 
drivers and _doc files. 

Xchange provides a multitasking environment, has commands of its own; 
Set which allows the default data drive and Help file drive to be 
changed; Output which controls printing a document as a background 
task while you continue working on either of the four programs. TSL 
is another command which stands for Task Sequencing Language. Seeing 
this in action will astound you! There are a series of TSL files on 
the disk. 

My advice is to load Xchange. When the Xchange screen appears, press 
CTRL/C, then F3, T. A prompt will appear on the command line; enter 
TUTOR and then press enter. A menu will appear at the top of the 
screen offering a tutorial for each of the Tasks (Quill, Archive, 
lUaacus and Easel). Press the appropriate letter for the task and 
Xchange will load and run the tutorial file of your choice. 

Quill has several new commands: Glossary which allows the user to 
designate a character to be used as a 'Macro*. Export, which will 
output the current file in memory to be printed to a file in ASCII, 
without any control characters attached (except carriage return). In 
other versions you could do the same thing when printing to a file 
instead of printing to a printer. However, when you choose this 
option the user had to remove the disk with the printer driver on it 
so as not to have any printer control characters embedded within the 
file. 

There is a Mail Merge facility included within Quill and another 
command called Extract, which operates much like the copy command but 
will allow you to save blocks of text to a disk so that they may be 
merged into other documents. 

If I have interested you in the Xchange suite, you can send me a 
formatted 720K disk (either 5 1/4" or 3 1/2" diskettte), with return 
postage (normally 75 cents for one disk) and encolsed in a decent 
envelope which can be used for the return mail, I will copy the 
entire disk for you and mail it back to you. I have a disk with the 
Xchange HELP files formatted into _doc files which makes life a lot 
easier when printed out on paper instead of reading the Help files on 
a screen. If you want these files include an additional formatted 
720K disk - the postage for both disks usually runs at 90 cents. 
See you next month.... Bob Gilder

North America 



First Time Procedure For Your Z88 



First Time Start Up: 

Follow these instructions only when the Z88 has been without any power 
and must be fully reset and initialized. You should never have to follow 
these instructions more than once— the first time you put batteries in the 
Z88. Thereafter, the Z88 provides plenty of baclcup internal power to let 
you change batteries without resetting the computer. 

1. Install the batteries following the Batterv Installation instructions 
below. 

2. With a paper clip or fingernail file, press the small grey button on the 
left side of the Z88. It is in a small square hole next to the round hole 
for the AC adapter plug. The screen on the Z88 will stop fluttering 
and sparkling once the button has been pressed. 

3. If the screen goes blank after pressing the button, turn the Z88 on by 
pressing both "SHIFT* keys at the same time. 

4. Press the key just to the left of the space bar, then press the "S" 
key. This brings up the CONTROL PANEL display. 

5. Use the various arrow keys to move the small blinking cursor (black 
box) around in the panel until it is sitting on the "E" in the word 
"European". Then press the "A" key followed by the "ENTER" key. 

6. Next, set the date and time by pressing the key followed by the 
"T" key. To set the date, press the "-►" key to move the cursor to the 
word "SET" and press the "ENTER" key. Type the date, but do not 
press the "ENTER" key when done. Instead, press the "I" key to move 
to the time. Type in the time and press the "ENTER" key. 

7. Press the "ENTER" key again to exit the Clock function. 

AC Adapter Use: 

Use a 6 volt adapter with a 300mA or 500mA current rating only. The 
polarity must be correct. The inside of the plug must be positive and the 
outside negative. Double check these three characteristics: voltage, 
current, and polarity, before connecting any AC Adapter to your Z88. 
This is especially true if you choose to use an adapter that lets you switch 
voltages or polarity. 

Battery Installation: 

Make sure you install all four AA batteries in the direction indicated. 
Insert one battery at each end of the tray. To insert the middle two, form 
them into a "V" shape with the legs in the tray and press down on the 
point of the "V" until the batteries seat themselves firmly. Always keep 
batteries in your Z88. This will protect your data even if you are using an 
AC adapter. 

Using the American Dollar: 

The spreadsheet application, PipeDream, assumes the British pound for 
currency. To change to the American dollar while in PipeDream. press 
the following keys in order: "o" (above the left SHIFT key), "O" (oh), 
"ENTER" (press twelve times), "$", "->", "DEL", "ESC". 



Using CompuServe, America's Computer Utility: 



Make sure that you set the Z88 up with the correct protocol for the baud 
rate you will be using. To do so, press the "□" key followed by the "S" 
key to get to the setup panel. In the right column are the communication 
parameters. Set the first two entries to the correct baud rate, set the third 
entry. Parity, to "S"pace and the last entry, Xon/Xoff, to "Y"cs. 

To dial using the terminal application, type the four letters "ATDT** 
followed by the phone number and press "ENTER". (If calling from a 
rotary dial phone, the first four keys to press are "ATDP".) 

While communicating with Compuserve, there is a tendency for the 
information to scroll off the screen. To prevent this, once you are in the 
service, keep your left little finger resting on the "o" key. With the index 
finger of the left hand, press "S" to Stop the screen from scrolling, and 
press the "Q" key to resume scrolling. 

Until you are familiar with using the Z88 as a terminal, it is recom- 
mended that you always use the lowest baud rate your modem is capable 
of processing. 

Using other Communication Services: 

Most services are similar to Compuserve. Besides the above instructions, 
make sure you follow the procedures laid down by the particular provi- 
der you are communicating with. 

If the Screen is Hard to Read: 

On the left edge of your Z88 is a knob for brightening the screen and 
making the letters darker and more easy to see. Packaging the ZS8 tends 
to rub the knob toward the lightest setting. To brighten the screen, adjust 
the knob until the letters can be read comfortably. The best setting is 
just before the entire screen darkens. This provides the best contrast.

ePECIAL NOTE OAJ LiPDATE ISSUE DISKS 

Some of the issue disks v^ have been offering have not been updated in awhile, or it has been 
awhile since we sold some of them. Starting with the next issue of UPDATE (the January issue), those 
vuhichwehavenothad updated for some time, or had little or no response on selling will be dropped from 
our offerings. Some that appear headed in that direction are the ones by Bill Jones and Bill Pedersen, as 
they are not subject to updates anylonger. Upuntil that time they are offered at $5. 00 off of theprices 
they are listed for on the back pages This also applies to the Cable and Hartung disks. We will also be 
dropping the Aerco disk offerings. I had several of you askme to include Aerco disks, sol did. but no one 
ever ordered one. We will of course be replacing thesewith newdisks. For this short time take ad vantage 
of this price reduction and getsomegood North American generated Sinclair software. Perhaps wecould 
sell some Aerco software here if someone would submit it for us to give it a try. New stuff. 

This issuewe do have some titles that have been updated by Al Feng, and we have added another 
disk of good sharevvare and PD software for theOL to theOL Compendiom set. These prices remain the 
same If you have purchased thecompendiom and want the extra disk, justletus know and include$3to

Larry Crawford / 357 Reynolds Rd / London Ontario Canada N6K 2P8 
(519) 657-9119 PUBLIC DOMAIN 12 Oct 93 



If you went for a 24-pin or bubble jet printer and had 
thoughts of trying to print some graphics in the 24-pin bit 
image mode, you were probably somewhat taken aback by the 
apparent comlexity of it all, just as I was. 

This article should take some of the mystery out of the 
process. The demo program will give you the information needed 
to develop your own applications. 

BACKGROUND 

The 24 print head pins are arranged into three groups of eight. 
In effect, each group acts as a separate 8-pin head covering 1/3 
of a print line. Thus, with one pass it is possible to achieve 
the vertical definition of three 8-pin passes with only one 
pass. Furthermore, it is possible to achieve a density of 360 
dots per inch in Hex Density mode. 

These attributes make the printing very fast and should allow 
a CAD program to produce printed circuit board layouts with good 
solid lines without the need for multiple passes. Unfortunately, 
the existing CAD programs that I have seen are all based on 72 
dots per inch (dpi) horizontal density and 8/72" vertical line 
spacing. The 24-pin printer does not have the 72 dpi option. 
Instead, it uses multiples of 60 dpi and 1/360" paper feed. This 
makes the size of the printed image larger than that produced by 
an 8-pi n pr i nter . 

Consequently, it cannot be used by software programs such as 
Pixel Print or CAD in their present form: a) two columns of 64 
characters will not fit side by side on a page and b) the socket 
hole spacing on a pcb layout would be too great. It should be 
possible to modify the calculations performed by a CAD program 
to get the scale of the final image correct. 

There are numerous other applications, of course, so feel free 
to make use of the information that follows. 



As a demonstration, we will print the first line of the screen 
in 24-pin double density bit image graphics. The data in the 
conversion chart that follows is essential to the process. 



Type in the following program (without the parenthetic comments, 
of course) : 

5 REM 24-pin bit-image demo 
10 CLS: PRINT "QWERTYUI0PASDFGHJKLZXCVBNM1 23456"

[An important reminder since the screen will go blank and 
nothing will happen if the printer is not ON. 
<INPUT;> is a simple way to clear out the bottom of the 
screen ]

["b1" is the "top" byte. Following the chart, if the top 3 
pixels of the screen are INK then the value assigned to "b1" 
will be 224+28+3=255. Therefore, all top 8 pins of the print 
head will fire] 

60 LET b2=128*P0INT ( x , y-2 ) + 1 1 2*P0I NT ( x , y-3 ) + 1 4*P0I NT (x,y-4)

["b2" is the "middle" byte. Following the chart, if the

Therefore, the middle 8 pins will all fire] 
70 LET b3=192*P0INT (x,y-5)+56* POINT ( x , y-6 ) +7*P0I NT (x,y-7) 
["b3" is the bottom byte. Following the chart, if the pixels 
6th, 7th & 8th from the top of the screen are INK then "b3" 
will be assigned a value of 192+56+7=255. Therefore, the 
bottom 8 pins will all fire] 
80 RESTORE 80: GO SUB 500: NEXT x: DATA b1 , b2 , b3 , b1 , b2 , b3 , 999

[send CARRIAGE RETURN and Line Feed] 

500 READ a: IF a=999 THEN RETURN 

[999 is a dummy value to signal the end of current data] 

510 IF IN 1270236 THEN GO TO 510 [if the printer is busy, wait 
until it is ready for data, (<INPUT;> is a simple way of 
clearing the bottom 2 lines of the screen)] 

520 OUT 127, a: GO TO 500 [send data to the printer] 

9999 RANDOMIZE USR 100: SAVE "lldem.BI" 



Now <G0 TO 9999> to save it to disk and then <RUN> 

It takes nearly a minute to get to the actual printing because 
of all the calculations to be done in BASIC. 



If you want to print a whole screen, make the following changes: 
LINE 10: Replace with: 10 LET ctr=0: RANDOMIZE USR 100: LOAD 
"screen name" SCREENS 

['ctr' will keep track of the print line being 
processed] 

LINE 40: Replace <LET y=175> with <FOR y=175 TO 7 STEP -8: LET 
ctr=ctr+1 : > 

[This will set up a loop to deal with all 22 screen 

lines and increment the line counter] 
LINE 90: Add <ctr;",";> immediately after <PRINT #0;> 
LINE 100: Add <NEXT y:> immediately ahead of <STOP:> 
LINE 9999: Change program name 



LINES 40 and 100 set up a loop to look at all 22 lines of the 
upper screen, outputting the data to the printer at the end of 
each line. A full screen takes over 20 minutes to copy. 



To print out in triple density, change the data in line 30 to 
27,42,39,0,3 and add another set of b1,b2,b3 to the data in line 



45 



80. The printer will then expect 3x256 bit image data bytes. 



A much faster version gets the data from the screen file 
instead of the screen. It puts the data into 1 or 22 line files, 
ready to be loaded from disk then sent to the printer by a 
205-byte m/c routine. It takes about 5 minutes to create and 
save the 22 files and less than one minute to print them all in 
triple densi ty . 

I will be happy to send you a copy of this utility on a 
5-1/4" double sided floppy in either Oliger or LARKEN format for 
$5.00 cash or money order. Be sure to state which DOS. 



A full screen produces an image 4.25" by 2.9" (10.8 by 7.4 mm) 
and is proportioned so that squares are square and circles are 
round. Different screen images can be printed consecutively on 
the same sheet so that a composite image can be 4.25" by any 
1 ength .

HINTS & TIPS 




The Z-88 has an almost 
unprecedented array of op- 
tions to expand its available 
memory. For the user new to 
computing or to the Z-88, 
there may seem a bewildering 
choice. Which is more suitable? 
With the chance of making a 
costly mistake, advice surely is 
needed. 

AM;W The Z.88 has 32K of built- 
in RAM of which about 20K is 
usable. That means it can store 
20,000 characters of information, 
which amounts to 3,000-4,000 
words or roughly »five pages of 
text. The RAM acts as everyday 
memory and the disc memory of a 
larger computer. It is by far the 
most versatile expansion and 
would be the most natural first 
choice for the majority of users. 

The RAM may be expanded by 
adding extra packs which slot in 
the front. There are three slots, 
each of which can take up to iMB 
of RAM but the largest pack 
available at the moment is 128K. 
So, in theory, one could have three 
I28K packs which together with 
the computer internal memory 
would give 404K. This, however, is 
not recommended for two 
reasons. The power drain of the 
three RAMS, especially the one in 
the third slot, would reduce 



battery life significantly. There 
would be no spare slots for any 
other kind of pack to be used. 

Many users find 128K satis- 
factory; if you want much more 
immediately-available memory, 
Cambridge Computer is produc- 
ing a 512K RAM pack in March. 

Because of their nature, RAM 
packs cannot be removed from 
the Z-88 without losing their 
contents. RAM packs take extra 
current from the Z-88 batteries. A 
128K pack in slot i or 2 will take 
about 15 percent more and, 
paradoxically, the 32K slightly 
more than that. The 512K will take 
the same as the 128K. 

EPROM.The second type of 



There is no fundamental reason 
\v h y y 0 u c a n not u s c. 
rc( liari;<'al)lc l)alt(Mic.s with tlir 
Z-HH, as many people have dis- 
covered, but there are two points 
vou should lake into account carefully 
belorr deciding to use tliciir 

You will not get nearly 20 hours of 
life from them. This is because of the 
lower maximum voltage (5 '^V'} of ni- 



pack the Z-88 can use is EPROM 
— Erasable Programmable Read 
Only Memory. They can only be 
used in slot 3 and are used for 
backing-up important data or 
programs from the Z-88 RAM. 
They will retain their data even if 
they are removed from the Z-88, 
so in addition to back-up they are 
also ideal for transfer of infor- 
mation between Z-88s. 

There is one snag with 
EPROMs; data is effectively burnt 
on to then and cannot be erased 
selectively. When the EPROM is 
full, one must copy across 
important data to RAM and place 
the EPROM in an EPROM 
ERASER, which completely wipes 
it. It is them ready for filling 
again. Thus due to the nature of 
EPROMs, if you have a file on the 
EPROM you have altered, you 
must 'blow' an entirely new copy 
on to it — you can use the same 
name though, the old one becom- 
ing effectively useless until 
erased. 

ROM: The third, and least 
common at the moment, kind of 
card is a ROM card. This would 
contain an external application, 
for example, a database or 
communications program. It 
woidd be integrated with the Z-88 
operating system, so one could 
call it from the INDEX as if it 
were built-in; it would use the 
same Menu and Help system. 

Technical note — What the Z-88 
terms a ROM card may techni- 
caUy be a ROM or EPROM. The 
difference between that and a Z-88 
EPROM lies in what has been 
programmed into its header, so 
that the Z-88 knows that it must 
run an ROM, and can save data on 
to an EPROM. 



cad cells and the fact that, even when 
fully-charged, they contain less energy 
than alkaline cells. 

The voltage against time graph for 
ni-cad cells tails off very quickly after a 
certain time, the upshot of this being 
that you could leave your seemingly 
healthy batteries in your Z-B8 in sleep 
mode for a few days only to return and 
find them completely dead
